Eaton Specification Sheet - EDSC21101 W31
Feraloy iron alloy enclosure provides rugged, durable protection in harsh environments, reducing long-term maintenance costs and downtime while extending service life in chemical, petroleum, and mining applications. The business impact is lower total cost of ownership through fewer field replacements and safer operation, enabling uptime in critical processes such as pump skids and conveyor controls in hazardous locations. This unit’s compact single-gang, 3/4\" trade size hubs simplify panel routing and wiring density, accelerating installation and reducing labor costs for new builds or upgrades. Through-feed configuration with two 3/4\" hubs supports flexible line routing, while the built-in 7.74A Cutler Hammer heater provides reliable overload protection without external add-ons. The 1 hp motor rating covers a broad range of auxiliary drives, delivering dependable performance without over-sizing equipment. Its compatibility with the EDS family preserves stock and simplifies spare-part planning for plant-wide standardization. The design also meets NEC/CEC compliance and hazardous-location ratings, complemented by a NEMA 9 enclosure, which aids documentation, inspection readiness, and certified safety for industrial projects. In real-world terms, installers gain faster commissioning, while maintenance teams benefit from consistent, predictable protection across both routine and emergency scenarios.

FAQs
The EDSC21101 W31 is a through-feed, single-pole control station built for hazardous locations. It uses two 3/4" hubs and a single-gang enclosure, simplifying wiring density and panel routing. For installation, mount in a compliant enclosure, connect the motor and line conductors per NEC/CEC guidelines, and verify the integrated heater is functional. This minimizes field wiring time and ensures immediate protection against overloads.
This model carries NEC/CEC compliance with hazardous-location ratings: Class I Division 1 and 2, Class II Division 1 and 2, and Class III. It also features a NEMA 9 3 7 enclosure rating, signaling robust protection against dust, moisture, and corrosive atmospheres. These certifications simplify regulatory acceptance and documentation for plant-wide safety programs.
Yes. The unit is rated for 1 hp motors and supports a through-feed configuration with two 3/4" hubs. The design facilitates straightforward wiring, reliable start/stop control, and integrated overload protection via the built-in heater, making it suitable for common, small-to-medium motor loads in hazardous environments.
Feraloy iron alloy provides high strength and corrosion resistance, extending life in aggressive environments. This reduces maintenance cycles and replacement parts. For installations in chemical processing or oil and gas facilities, the rugged housing supports long service intervals, minimizing maintenance interruptions and improving overall equipment availability.
ROI comes from lower maintenance costs, reduced downtime, and easier compliance audits due to NEC/CEC ratings and the NEMA 9 enclosure. The integrated heater and compact wiring reduce labor costs during installation and commissioning, while the durable construction lowers replacement frequency in hazardous locations, delivering predictable operating costs over the asset life.
